EASEMENT, ACCESS TO LIGHT, OBSTRUCTION OF CHIMNEYS, LACK OF SUPPORT, NOTICE OF ACTIONS, CONSENT, FALSE REPRESENTATIONS, EQUITABLE DEFENCE, REPLICATION
Facts
The plaintiff complained that the defendant had obstructed the light and air from entering his antient windows, that the defendant had built walls and buildings, which prevented the smoke and vapour from the plaintiff’s chimneys from being carried off and that by pulling down some adjoining buildings belonging to him, the defendant had deprived the plaintiff’s house of the support he was entitled to. The defendant pleaded by way of equitable defence that the grievances that the plaintiff raised were occasioned by the pulling down and rebuilding of her house. The plaintiff was given notice of the defendant’s actions. The defendant believed that her house was pulled down and a new one erected with the knowledge, acquiescence and consent of the plaintiff. The plaintiff argued that he agreed to the building work upon the faith of false representations by the defendant and her agents. The way in which the work was presented to the plaintiff was not such as to result in such damages.
Issues
(1) Did the defendant’s excuse amount to a defence to the plaintiff’s claim?
(2) Was the plaintiff’s reply a good response to the defendant’s excuse?
Decision/Outcome
The decision was in favour of the plaintiff.
(1) The defendant’s excuses amounted to an equitable defence because if someone conducts himself so as to induce another to believe that he has given his consent to some building work being carried out, and the latter spends money upon the faith of such consent, the former has no right to withdraw his consent afterwards.
(2) However, the equitable defence of the defendant was nevertheless well answered by the plaintiff. The replication, therefore, took away from the defendant the equitable defence that she relied upon.

This article summarises the 1861 case of Davies v Marshall (1861) 10 CBNS 697, a nineteenth-century common law authority on easements, obstruction of light and air, support, and equitable defences based on acquiescence and consent. The case itself is a historical authority and its core legal propositions remain part of the wider common law landscape.
The equitable principle described in the decision — that a party who by conduct induces another to believe consent has been given to building works, and the other acts on that belief by spending money, cannot afterwards withdraw that consent — reflects the doctrine now generally understood as proprietary estoppel or estoppel by acquiescence. This doctrine continues to be recognised and applied in English law: see, for example, Thorner v Major [2009] UKHL 18 and Cobbe v Yeoman’s Row Management Ltd [2008] UKHL 55, which affirmed and refined estoppel principles. The underlying reasoning in Davies v Marshall is therefore consistent with current law, though modern analysis of such disputes would be conducted within the developed framework of proprietary estoppel rather than the older pleading terminology of ‘equitable defence’ and ‘replication’ used here.
Readers should note that the law of easements, particularly rights to light, has been significantly developed since 1861. The Rights of Light Act 1959 governs the registration of notices to prevent acquisition of rights to light by long use. The Law Commission has also examined rights to light, publishing a report in 2014 (Law Com No 356) recommending reforms, though these recommendations have not been implemented by statute as of the date of this note. The article is accurate as a summary of the 1861 decision but should be read as a historical case note. Modern disputes concerning rights to light or acquiescence would be resolved by reference to the considerably more developed body of statute and case law that has accumulated since.
